Leased Lines are dedicated connections between yourself and a datacentre or internet service provider. Leased Lines are used to connect geographically dispersed offices or with the addition of IP Transit are used to provide internet connectivity to a leased line.
Leased lines range in size and scope but generally range from 10Gbps to 10Mbps with varying subscriptions in terms of internet access bandwidth and are delivered as fibre or copper. Leased lines do not have contention ratios usually found in broadband technologies and are completely private connections between your organisation and the provider. In terms of cost and flexibility leased lines are location dependent with inner city areas benefiting from substantial cost savings.
Leased Lines provide a fantastic way to connect to the internet or connect remote offices. Below are listed some of the highlights of leased line services.
Leased lines are dedicated private connections that are not subject to contention ratios. Although contention is still possible at your providers internet peering point if they have oversubscribed there IP transit peering.
Whilst leased lines are delivered by very few suppliers the ISP community has regulated access to prices which means more choice in terms of providers.
Today there are many leased line products and services being deployed. For rural regions it is still possible to get cost effective leased lines if your exchange has been enabled by a service provider.
Unless you’re using a connection around the clock you will have spare capacity to potentially backup other systems and services to the colocation provider where your leased line terminates.
Leased lines are configurable to allow for QoS or quality of service parameters to be set to ensure mission critical traffic gets access priority. Leased lines are particularly suited to customers wishing to exploit internet telephony services.
With any technology deployment such as leased lines there are things to keep in mind and consider. We have listed out potential pitfalls to consider when purchasing any leased line service.
Your service level agreement provides guarantees for uptime availability from your provider, always check that your provider has stable internet connectivity and a history of adhering to SLA’s.
Whilst being an extremely stable product, leased lines are subject to failure due to fibre cuts or a datacentre outage. If budget permits use a secondary ADSL or SDSL service as a backup to your main connection. Your routing hardware may be configured to automatically failover in the event of failure with minimum disruption to users.
Leased lines are generally sold on 1, 3 or 5 year terms. As connectivity options mature and new products are deployed, it is advisable if you’re using a long term contract to build in upgrade or technology switching options.
Not all bandwidth is created equal. Always ask for details of peering arrangements and test latency by doing trace routes.
Unless your company has provider independent (PI) addressing, when migrating to a new provider you will have to re-apply for new IP addressing, this may affect your internal systems.
